Abstract

PURPOSE:To check a flow passage opening to both bath and shower sides simultaneously, by attaching an on-off valve, which opens or closes in linkage with a bath side valve or a shower side valve, to a mixture chamber. CONSTITUTION:When a shower side valve B is closed if a lever handle 70 is pressed down, combined hot and clod water is discharged out of a water discharge device 14. Under this condition, if a control handle 40 is operated and thereby the shower side valve B is opened, a coupling part 84 of an on-off valve body 80 is positioned inside an opening 42 whereby a first mixture chamber 9 and a shower side chamber 12 are interconnected through by a flow passage F. Simultaneously with this interconnection, a second annular body 83 blocks up a passage port 48, closing the flow passage leading to the inside of a second mixture chamber 10, and the combined hot and cold water to be fed out of a control valve C is all fed to the inside of the shower side chamber 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a hot water mixer faucet that mixes and discharges hot water and water, and particularly relates to a hot water mixer faucet configured to discharge a mixture in two directions: the shower side and the bath side.

[Prior art]

Some conventional hot and cold mixing faucets have a spout that supplies water to the bath side and are also configured to supply water to the shower side. This system is equipped with a shower-side valve and a bath-side valve that are operated by separate handles on the downstream side of a control valve that manually adjusts the temperature by changing the mixing ratio of hot water to water. Water can be supplied at the same time.

However, for example, if the shower side valve is opened and the bath side valve is opened during use, the mixed water can flow out in two directions from the inflow side, so the flow path resistance is substantially reduced and the mixture is mixed. This causes a phenomenon in which the water temperature changes.

To explain this phenomenon specifically, the water pressure of the water supply source and hot water supply source that supplies hot water to the hot and cold water mixing faucet is generally higher on the water supply side.
For example, the water pressure Pc on the water supply source side is 2 kg/d, and the water pressure Pc on the hot water source side
) I is assumed to be approximately 0.5 kg/cII+. Here, if the pressure loss P1 based on the flow path resistance in the hot water mixer faucet when only the shower side valve is open is 0.3 kg/ci, then
The hot water supply pressure PK and PL in the hot water mixing company are respectively P I+ = PC-PI = 1.7 kg/cJ...
(11PL=PH-PH=0.2kg/cJ...(
2).

Under this water supply pressure condition, the opening degree of the control valve is adjusted, the mixing ratio of water and hot water is set, and mixed water at an appropriate temperature is discharged from the shower, but when the shower side valve is opened, the bath side valve is opened. When this happens, the flow path resistance decreases.

The pressure loss P2 based on this flow path resistance is 0.1 kir/cJ.
If deviated, water supply, hot water supply pressure PM, I'1. J is each P
M=PC-P2=1.9kg/Cra・H・(31
PN-P. -P2 = 0.4kg/ctA...
・(4) Here, if Rc and RH are the change ratios of the water supply and hot water supply pressure in the hot and cold mixer faucet before and after opening the lotus side valve, then Rc
= P M / P R = 1.1 ・ ・ ・ ・ (5)
RH=PN/PL=2.0 ・ ・ ・ ・(6
).

Therefore, the rate of change in flow path resistance on the water supply side is approximately twice that on the hot water supply side, but since the opening degree of the control valve is constant, hot water flows more easily and the amount of hot water discharged increases. This causes the temperature of the mixed water to rise.

Due to the above phenomenon, if the water supply pressure is higher than the hot water supply pressure and you open the bath valve while using a shower, there is a risk of high temperature mixed water being discharged from the shower equipment and causing burns. be.

[Purpose of the invention]

The purpose of the present invention is to provide a control valve that adjusts the temperature of mixed water by manually adjusting the valve opening, and to supply mixed hot water in two directions, the bath side and the shower side, and to connect the flow path in each direction. To prevent flow paths to a bath side and a shower side from opening at the same time in a hot water mixer faucet configured to be opened and closed by respective valves.

The technical problem to be solved by the present invention is that in the hot water mixer faucet with the above configuration, one of the valves on the shower side and the bath side (
If the other valve (referred to as the "second valve") is used while the "first valve" (referred to as "the first valve") is open, the supply of mixed water to the first valve is cut off and the second valve is opened. Either the mixed water is discharged only from the first valve, or the mixed water is discharged only from the first valve without being supplied to the second valve.

[Structure of the invention]

The configuration for achieving the above technical problem is to form an ice chamber and a hot water chamber each connected to a water and hot water supply source, a mixing chamber communicating with both chambers, and a shower side chamber and a bath side chamber communicating with the mixing chamber. , a control valve that manually controls the flow rate of hot water from the ice chamber and the bath room to the mixing chamber, and a shower side valve and a bath side valve that open and close the respective flow paths from the mixing chamber to the shower side room and the bath side room. The mixing chamber is divided by a partition wall into a first mixing chamber that communicates with the secondary side of the control valve and either the shower side chamber or the bath side chamber, and a second mixing chamber that communicates with the other side chamber. A vent is opened in the partition wall and linked to a valve in one side chamber that communicates with the first mixing chamber, and when the linked valve in the one side chamber is opened, the vent is closed, and when the valve is closed, the same is connected. It is equipped with an on-off valve that opens the vent.

With the above configuration, mixed hot water is not discharged from the shower side and the bath side at the same time. In addition, even if the valve on the other side is opened while water is being discharged in all conditions, water will be discharged only from one side or the other side, and therefore the mixed water discharge flow path will always be single. There is no large difference in flow path resistance regardless of the direction of water discharge, and temperature fluctuations caused by differential pressures of water and hot water supply pressures can be prevented.

〔effect〕

The present invention has the following effects with the above configuration.

i) - When operating the valve to use the water spouting part on the other side while spouting water from the example water spouting part, water is spouted only from one side, and water is not spouted from both spouting devices as in the past. , you can save water and hot water.

ii) Furthermore, the conventional mixing chamber can be divided into two parts by a partition wall having an opening, and it is only necessary to install an on-off valve that opens and closes the opening of this partition wall in conjunction with the pass-side valve or the shower-side valve. is easy.

The case (50) is the first case (51) and the opening (15a)
A second case (52) connected to the annular opening (13a) and a third case (53) located within the second mixing chamber (θO) are coaxially connected. 1st
The case (51) is inserted and screwed into the second case (52), and the valve shaft (54) is fitted with a spring (55) inside.
) so that it can be slid in the axial direction. Valve stem (
54) has a longitudinal hole (56), a cape hole (57), and a stroke adjustment hole (511) successively installed on the same axis, and a round hole (54).
57) is equipped with a spindle pushing rod (59).

The valve shaft (54) is connected to the main body (11) by a spring (55).
The tip is biased in the direction away from the first case (
It protrudes outward from 51).

As mentioned above, the second case (52) has an opening (
15a), a mixed water outlet (60) is opened in the bath side chamber (15), and a valve seat (6I) and a valve hole ((i2) are respectively formed in the second mixing chamber QOI). .

Inside the third case (53), which is coaxially connected to the second case (52), is a valve body (64) fitted with an annular packing (63) that approaches and separates from the valve seat (61). 65

66) are integrally installed.

The spring (65) biases the valve body (64) toward the valve seat (61), and when inactive, the valve body (64)
can remain seated on the valve seat (61). Furthermore, a mixed water inlet (67) is opened on the side of the third case (53) close to the valve seat (61), and when the valve body (64) is separated from the valve seat (61), the second mixing chamber ( The mixed water in +01 flows into the second case (52) through the mixed water inlet (67) and the valve hole (62), and then flows into the mixed water outlet (60).
It can flow down into the bath side chamber (12) and be discharged from the spout (14).

The third case (53) is open at both left and right ends, and a thin pressure reducing plate (69) with a small hole forming a small passage is attached to the end located inside the bush (13b). There is. Therefore, the storage space for the valve body (64) is divided into the second part by the small hole.

To open this bus side valve (C), lever handle (70)
When rotated downward, the valve stem (54) is pushed in the axial direction, and the spindle pushing rod (59) pushes the spindle (66). Due to this pushing motion, the valve body (64) fixed to the spindle (66) moves and opens the valve while discharging water in the pressure chamber (P) from the small hole. If the hand is released from the lever handle (70) in this state, the valve shaft (54) is returned to its original position by the spring (55), so that the lever handle (70) is also returned to its original position. At this time, the valve body (64
) gently seats on the valve seat (61) as the volume of the pressure chamber (P) increases due to water flowing into the pressure chamber (P) from the small hole of the pressure reducing plate (69), and Valve (C) closes. Therefore, the bus side valve (C) is connected to the lever handle (70
) is released, a certain amount of mixed water is discharged and the valve is automatically closed.

In the above configuration, first. When the shower side valve (B) is closed as shown in Figure 2, the lever handle (7
0), mixed hot water is discharged from the water discharging tool (14). In this state, if you want to use the shower, operate the operation handle (40) and use the shower side valve (B).
) When the valve is opened, the connection part (84) of the on-off valve body (80)
is located within the opening (42) as described above, and communicates the first mixing chamber (9) with the shower side chamber (12) through the flow path (F). At the same time, the second annular body (83) opens the opening (4).
8) is closed to close the flow path into the second mixing chamber (1 (O),
All mixed water supplied from the control valve ('C) is supplied into the shower side chamber (12).

In this mixed water flow, when the water reaches the first mixing chamber (9) through the control valve (C), it only flows down in one direction, either the shower side or the bath side, and is discharged from both at the same time. There isn't.

Therefore, even if the lever handle (70) is pressed while the shower is in use, the mixed water only flows from the first mixing chamber to the shower side chamber (12), and the flow path resistance is constant, as described in the conventional example. It is safe to use because high-temperature water is not discharged as described above.
